HAllDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



Specimens.— We have to request the patience of various 

 of our correspondents wlio have sent us specimens to name. 

 This department of the Editor's duties has been greatly en- 

 larged, and it is novif impossible for us to insert all the 

 answers in each month's number. We have many by us, 

 ready for insertion, and others which are in the hands of such 

 scientific gentlemen as gratuitously assist us in this depart- 

 ment. 



X. w. O.—Grenllea is edited by Dr. M. C. Cooke, and is 

 published in sixpenny monthly numbers. You cannot do 

 better than procure it for the purposes you name ; viz, as 

 the authoritative journal on all matters relating to micro- 

 botany. 



D. Travebs. — The specimen sent is a crystal of selenite 

 (sulphate of lime), not of carbonate of lime, as you sup- 

 posed. 



T. SoMERS.— Newman's " British Moths " and " British 

 Butterflies" are now published by R. Hardwicke, 192, Pic- 

 cadilly, London, in parts or volumes. 



R. T. W.— We cannot undertake to return rejected MSS. 

 unless stamps are lorwarded for the purpose. 



Sigma.— Get Staveley's "British Spiders," published by 

 Lovell Reeve & Co. at 10s. 6d. 



George M. — Your fossil is a coral, not a plant, and is 

 called Lithostrotion /jusaltiforme. 



P. Q. R.— Your mosses are as follows: No. 1, Didymodon 

 purpnreum ; No. 2, Dicranum rvfescens ; No. 3, Dirranum 

 taaifolium ; No. 4, D. pellucidum; No. 5, Tortula convoluta; 

 and No. 6, Weissia nirrata. 



J. P. Taylor.— Get the new edition, with additional chap- 

 ter on the Polariscope, by F. Kitton, or Lankester's " Half- 

 Hours with the Microscope," London: Hardwicke. It will 

 give you the best account you can obtain of the polarization 

 of light. 



Emily T.— Your ferns are : No. 1, Cystopterii fragilis ; No. 

 2, Polystichum Lonchitis ; No. 3, Lastrea oreopteris; No. 4, 

 Athyrium filix-foemina ; and No. 5, Lastrea dilatata. 



R. ScoRESBY.— Consult Dr. Masters's "Vegetable Terato- 

 logy" for anything relating to the monstrosities of plants. 

 The work was published by the Ray Society, and is certainly 

 not only the most exhaustive, but the most philosophical 

 treatise on this difficult subject in the English Language. 



Could Mr. Barkas or any reader inform " W. M." where 

 he could obtain the Stanhopescope lens (or a similar one) 

 referred to in " Gossir " No. for October, 1866. p. 234 ? 



L. S. and J. C— The caterpillars of the Lackey-moth spin 

 webs like those on the leaves of the Hazel. It was these, 

 and not the caterpillars of the Processionary Moth, that had, 

 doubtless, produced the " excrescences;" 



E. LovKTT. — It is not unusual to find fossils embedded in 

 flint in the manner you describe ; indeed, that is the normal 

 condition in which they are found in flint. No geologist now 

 doubts that the flint whs originally soft and jelly-like. Your 

 oolitic specimen is from one of the many beds in the " Port- 

 land Series." 



G. F. Barker.— Exchanges are not charged forunless they 

 exceed the length of three lines. 



T. Buck. — The so-called " Unicorn's horn " is the single 

 tusk of the male Narwhal [Monodon monoceros). 



S. T. P. — We are sorry not to be able toinsert your notices 

 earlier, but we cannot depart from our rule of priority , except 

 under unusual circumstances. 



A. L.— Perhaps some of our bee-keepers will inform this 

 correspondent what is "the best food for bees in a barren 

 land, where no flowers are found for miles ! " We get a good 

 many natural history conundrums, but never had a more 

 puzzling one. 



W. Lee. — Your specimen is the Mouse-ear Hawk-weed 

 {^Hierncium piloteltii). 



T. Cooper. — The odoriferous orchis is the Sweet Conopsea 

 {Gymnadeniii ranop-'ea) ; the other species is the common 

 spotted orchis (Orchis maculata). 



J. C. R. — No. 1 is a group of the "Oaten-pipe" 

 Coralline {Tubvlari)i iyidimsn) ; No. 2 the empty egg-cases 

 of the common whelk (liuccinum undalatum) ; No. 3 the Ele- 

 phant's-tusk shell (Dentaiium cntale). 



G. GuYON. — The " masses of green jelly," &c., alluded to 

 by this correspondent as being "attached to various sea- 

 weeds," may he as follow.s :— The little sessile masses are the 

 oothecx or egg-masses of Littorina, and the pedunculated, 

 of Trochus. When the former are placed in sea-water, the fry 

 of mollusca appear : from the latter little oval bodies escape, 

 which swim vividly by means of a circle of cilia, and have, 

 apparently, two eye- specks. We think the ova of Turbn are 

 deposited singly in sea- weed, and are somewhat hat-shaped 

 in form.- J{. (?. 



F. OsBORNK. — It is authoritatively stated (we have not 

 tried the experiment) that the Japanese Lily (Zilium auran- 

 tium) will effectually keep away house-flies ; at any rate, no 

 one will complain of the sweet odours of this plant.
